The carton comprises a body portion having four sides, 1, 2, 3, 4, and four flaps, 5, 6, 7, 8, at,one end thereof, and four flaps 9, 10, 11, 12, at. the other end thereof.

Several coacting mechanisms are employed to act upon the cartons to first feed the cartons along a supply magazine in their collapsed condition; to feed the cartons one by one into the machine in their collapsed condition; to operate upon each carton to open the same; to fold and seal the flaps at one end thereof;'to exert pressure on the carton and to eject the carton with the flaps at the other end thereof unfolded so that the carton will be ready for filling.

The construction, form, arrangement and operation of the several mechanisms will now be described.

A suitable drive shaft 13 is mounted in the machine frame and it may be driven from any suitable source of power not shown herein. This main drive shaft 13 drives an auxiliary shaft 14 through gears 15,16. The several operating mechanisms other than the suction and air discharge devices are driven from this auxiliary drive shaft 14 as will hereinafter appear.

The carton supply mechanism will be first described. A vertically arranged magazine 17 is provided for the collapsed cartons. An endless carrier is provided for moving the stack of collapsed cartons upwardly along the magazine 17 to bring the uppermost carton into position to be fed into the machine, which endless carrier comprises side chains -18 passing around upper and lower sprockets 19, 20, on cross shafts 21, 22, which chains are provided with shelves 23 arrangedto be brought into their supporting position while passing upwardly along the supply magazine 17, by means of studs or rollers 24, arranged to travel along a vertically arranged cam 25.

This rock lever 39 is also provided with a roller 44 arranged to engage the upper combined feeding-in and opemng-up suction nozzle, to lift the arms 41 from their engagement with the top of the stack of collapsed cartons when the said nozzle is at the limit of its forward movement, as will hereinafter more fully appear.

The suction means for feeding in. and opening up the collapsed cartons, is constructed, arranged and operated as follows: The upper suction nozzle 45 is provided with a feeding-in mouth 46 at its front end and a carton opening-up mouth 47 at its rear end, said mouths opening through the bot- The upper nozzle is also provided with aidownwardly and forwardly inclined top 49 arranged to engage the roller 44 on the rock lever 39. This upper nozzle 45 has a carriage 50 which reciprocates horizontally in a right line in guides 51 in the side frames of the machine. This upper nozzle is connected through a flexible pipe 52 to any suitable air exhausting means, not shown herein.

The lower nozzle 53 has an opening-up mouth 54 arranged to coact with the opening-up mouth 47 of the upper nozzle 45. This lower nozzle has a vertically reciprocating movement in a carriage 55 which re ciprocates horizontally in a right line parallel with the carriage 50 in suitable guides 56. The nozzle 53 is provided with a cross pin 57 projecting through its side walls and through vertically elongated slots 58 in the cross pin is provided with rollers 59 traveling in cam grooves 60.

The former suppending from the rod 64 at the rear end ply magazine 85 has its lower end arranged thereof. This stop 73 is furthermore pro in position to direct the bottommost former vided with rear and front shoulders 77, 78, of the stack onto the top of a carriage88 at 90 arranged to engage the opposite faces f th one side of the path of travel of the cartons, arm 70 of the bracket 71. This lost motion which carriage reciprocates horizontally in connection between the carriages of the upa right line on a frame bar 90. This carper and lower nozzles and the rock lever 61, riage 88 is reciprocated from the rock lever operates to bring the mouths 47 and 54 of 61 through a rod 91 connected at 92 to the the upper and lowersuction nozzles oppocarriage 88 and at 93 to the stop 73 carried site each other as .they reach onehalf of by the rod 67 of the lower suction nozzle their rearward travel; the remainder of 53.

When the opened-up carton is gages a: stud or roller 105 carried by an arm removed from between the opening-up 106, one end of which is connected at 107 months of the upper and lower suction nozto the plate 99 and the other end of whichis zles, the stop 82 will be forced below the hinged at 108 to the carriage 88,

form 111. The free end The carriage 88 is provided with an extension 109 to which is hinged at 110 a platof this platform is raised and lowered by means of a toggle lever connection 112, 113, a projecting arm 114 of which is arranged in position to be engaged by a stop 115 as the carriage reaches the limit of its forward movement for raising the platform and by a stop 116 as the carriage reaches the limit of its rearward movement for lowering the platform.

The opened carton, with its former inserted therein, is moved rearwardly from between the suction nozzles to a point beneath the bottomof the pressure magazine 86 by a reciprocating device comprising two plates 117, 118, provided with spring-pressed latches 119, 120, which are arranged to be depressed when the plates 117, 118, are moved forwardly beneath the opened-up carton and its former and are arranged to snap upwardly into position to engage the front side of the opened-up carton as the plates 117, 118, reach the limit of their forward movement. These plates 117, 118, reciprocate horizontally in a right line in suitable guides 121, 122, and the rear ends of the plates are connected by links 123, 124, to the depending arm 125 of a three-armed rock lever pivoted at 126 to the machine frame, another arm 127 of which lever is connected by a rod 128 to one arm 129 of a rock lever pivoted at 130 and the other arm 131, of which rock lever is connected by a rod 132 to an eccentric 133 on the auxiliary drive shaft 14.

One end of each former is provided with an uprising lip 134 and a recess 135. The lip 134 is arranged to travel in a groove 136 of an upper track rail 137 and a lower track rail 138 on the guide 122 is arranged to enter the recess 135 in the former to hold the former in position as the former and its carton are moved rearwardly from between the suction nozzles to a position beneath the pressure magazine.

WVhile the former is thus held, the flaps at the opposite end of the carton are subjected to the first three folding operations as follows: As the carton and its former are moved rearwardly, the flap 10 is folded by the stationary folding cam 139 and at substantially the same time the flap 11 is folded by the movable folding device, which device comprises a swinging arm 140 hinged at 141, which arm is held yieldingly at the limits of its outward and inward movements by a spring 142 connected at 144 to a lug of the arm 140. A tripper arm 145 is fixed to rock with the arm 140 and is arranged in position to be engaged by and swung rearwardly by a lug 146 on the nozzle carriage 50 and is adapted to be swung forwardly by a lug 147 carried by the connecting rod 64. The flap 12 is folded upwardly by the stationary cam 148. As the carton and its former continue their rearward movement, the inner face of the flap 9 passes over a paster disk 149 of a paste fountain 150, the shaft 151 of which disk is driven from a shaft 152 through a chain and sprocket connection 153, 154, 155. The shaft 152 is provided with a pulley 156 driven from any suitable source of power, not shown herein.

The three folded flaps are maintained in their folded position by their engagement with the vertical face of the cam 148.

The fourth fold and sealing of the flaps at the closed end of the carton is accomplished by the upward movement of the carton and former into the pressure magazine to be immediately described.v

The pressure magazine is open at its bottom and top and it is provided with an unyielding front wall 157, a yielding right side wall 158, a movable left side wall 159, and a movable back wall 160. The side wall 158 is yieldingly held at the limit of its inward movement by springs 161. The left side wall is moved inwardly and outwardly by toggle lever joint connections 162, 163, with a vertically arranged rock shaft 164, guides 165 being provided for guiding the side wall in its movements. The back wall 160 is moved forwardly and rearwardly by toggle joint connections 166, 167, with a vertically arranged rock shaft 168, a guide 169 being provided for guiding the wall 160 in its forward and rearward movements. The shafts 164, 168, are connected to rock together by means of rock arms 170, 171, and their connecting rod 172. The rock shaft 164 is provided with a two-armed lever 173, one arm 174 of which is arranged in position to be engaged by a cam 175 on the former carriage 88 to rock the shaft 164 in one direction, and the other arm 176 of said lever being arranged in position to be engaged by a yielding cam 177 also carried by the carriage 88 for rocking the shaft 164 in the other direction.

A vertically reciprocating plunger head 178 has its rod 179 resting on the end of the arm 129 of the lever 129, 130, 131. This rod 179 reciprocates vertically in bearings 180 of the frame. The head 17 8 is held from turning by side bars 181 connecting the head 178 with the arm 129 upon opposite sides of the plunger rod 179. The movement of the parts are so timed that the side and back walls159 and 160 are released from their pressure engagement with the stack of cartons and formers as the plunger rises and meets the bottommost former to force the bottommost carton and former up into the pressure magazine. This upward move ment of the carton will fold its fourth flap downwardly onto the other folded flaps and seal the same. The'movable side and back walls of the pressure magazine will be moved of its forward movement, its mouth 46 will movement into position to receive the next succeeding carton and former above the same. 7

A swinging latch 182 is hinged at 183 to a bracket 184 at the top of the"pressure magazine, which latch is arranged in position to engage the raised lip 134 on the projecting end of the former and tilt the other end of the former upwardly. While the former tilted position, the carton is blown from the former by a blast of air from a nozzle 185 arranged in position to direct the blast of air through the tubular center 186 of the former against the folded and sealed end of the carton. The air pressure 1s supplied to the ejector nozzle 185 through pressure supply, not shown; Intermittent blasts are provided for by a spring-actuated valve 188 in the pipe 187 under the control of a handle 189 arranged in position to be engaged by the reciprocating carriage. 88

to open tothe nozzle when the carriage 88 reaches the limit of its rearward movement. After the carton has been ejected from the topmost former, the. former is moved forwardly along the bridge 87 by a slide 190 reciprocating in a track 191 on a bracket 192, which slide is connected by a rod 193 to the upper arm 194 of the three-armed lever heretofore described pivoted at 126. The front wall of the former supply mag azine 85 at its upper end is provided with a yielding plate 195 for guiding the formers downwardly into the magazine.

It is to be understood that these formers 84 are entirely separate one from another and that a sufficient number of these formers I provide for a continuous contacting series of formers from the lower end of the pressure magazine 85. upwardly therethrough, along the bridge 87 and .downwardlythrough the former supply maga} zine '85 to the bottom thereof so that a former is supplied for each carton.

A general description of the operation of the different ,mechanisms of the machine on the cartons and formers is as follows: The

collapsed cartons are 'fed upwardly along the carton supply magazine 17 by the inter-' mittent movement of the endless carrier. As 1 the upper suction nozzle 45 reaches the limit 34 past the fingers 79 of the catch at the limit of the rearward movement of the suetion nozzle 45. The finger 79 engages the collapsed carton and. holds it on the table 34 until the mouth 47m turn engages it at the limit of the next forward movement. In

the meantime, the suction mouths 47 and 54 .the carton.

- into the recess 103 in the former,

a pipe 187 leading from a sourceof 'the' bridge and downwardly 'azi-ne 85 into position for use in connection with a succeeding carton.

of the upper and lower nozzles are caused to engage the upper and lower sides of the previously fed-1n carton and move the same inwardly and, atthe same time, open up As the nozzles reach one-half of theirrearward movement, a'former, which has been deposited onto the reciprocating carriage 88 from the former supply magazine 85, between the gage 94 and the spring actuated latch 96, will be forced into the opened-up carton by the inward movement of the pusher plate 99. The registering pin 101 will engage the end of the carton by passing the carton being thereby held in position on the former so that-the flaps at the opposite end of the 1carton will be properly folded on the scoring mes; The further rearward movement carton and its former will cause the folding the flaps 10, 11, 12, further rearward movement being accomplished by the engagement of the'latch 119, 120, therewith and the rearward movement of" the latch carrying plates .117, 118, the flap 9 being carried over and in contact with paster disk 149. When the carton and 1ts former reaches a position beneath the bottom of the pressure magazine 86 and above the plunger 178, the walls 159, 160, of

az1ne are released and the plunger 17 8 moves upwardly thus forcingthe carton and its brought into pressing engagement with thevcarton, thus serving to properly square up the carton and :seal the end of the same. It

is to beunderstoodthat the carton and its of the the pressure mag-- former in their step by step upward movement are subjected to a series of these pressures so that by the time the carton and its former reaches the top of the pressure magazine, a verycomplete and accurate sealing of the closed end of the carton 1saccomplished. As the carton and its former 1s' pushed above the top of the pressure magazine/the latch 182 will tilt the former and, at the same time, a blast of ejector 185 passing acting against the closed end of the carton will blow the carton from the former. As soonas this is accomplished, the slide 190 will. push the former along the bridge 87 toward the former supply magazine 85. The former will then proceed step by step along along the mag As the carriage 88 reaches the limit of its rearward movement, the platform 111 is lowered by the engagement of the stop 116 air from the. through the former and g with the arm 114 of the toggle joint connection. As the carriage reaches the limit of its forward movement, the stop 115 will, by its engagement with the arm 114, raise the platform 111. When the carriage and bottom former, as previously described, start on their rearward movement, the platform 111 will engage the bottom of the next former and lower it gradually by its passage along. the inclined plane thus provided, to the surface of the carriage 88 in position to be engaged on the next rearward movement of the carriage. 4

It will also be understood that if'the c0l-' lapsed cartons are being fed too rapidly upwardly along their magazine 17 the feeding of the cartons will be temporarily stopped by the coaction of the topmost carton with the arms 41 of the releasing device.

It will also be seen that these arms 41 are raised from their position on the top of the stack of collapsed cartons, by the engagement of the upper suction nozzle with the roller 44 at the time the suction nozzle is engaging the uppermost collapsed carton for feeding thesame into the machine.
